I'm going to put this on hold until vectorization (#6794) is merged or at least close to its final form., since it's quite clear from this discussion that an alternative index-based strategy for filtered aggregators would be implemented very differently with or without vectorization.
The configuration system to let users pick which strategy to use could be implemented now for query filters, though. I'm going to think a bit about that and open a new issue/proposal if needed.
